How does Formula One (F1) Rear Wing operate ?
Formula 1 Rear wing - F1 Tamizhan
Before the diffuser came into action, it was wing structures that were included in front and rear, which are called as front and rear bodyworks.
As we have seen in previous posts, more than 50% of the downforce is contributed by the rear body works, wing and diffuser.
What is rear wing?
The rear wing consists of two elements
1. Main plane
2. Adjustable flap
Both the elements are in the shape of inverted airfoil held together in position with help of endplates. The main plate does not move and remains fixed. The purpose of endplates are to compensate the resulting vortices formed from wing edges which we will see in the upcoming post. Here we explore the structure of rear wing and how does it work.
a. How does the main plane function?
It directs the clean air flowing over the side bodywork upwards thereby exerting downforce that makes the car to stick more to the ground. The whole design has to in such a way, the stall should not happen because of dynamic airflow through the wing. It means it has to designed for the optimum angle of attack.

b.Adjustable flap.
This is similar to the rear wing but smaller in size that works in harmony with the rear wing working together as a single unit.
The adjustable flap is pivoted at the end of the structure enabling it to adjust the vertical gap between the main plane and the flap ( up to 85 mm ).
This adjustable flap technique was introduced as a Drag reduction system to notch up racing experience. This also will be discussed in the upcoming post.

c. Lower rear wing
Prior to the current complicated design, there was a plane below the main rear wing closer to the diffuser which was operated to create a low-pressure area for the efficient functioning of the diffuser to draw out air at much more increased speed.
over the years, as diffuser designs evolved, lower wings disappeared.
